with handwheelcontrolflange

Advantajes of diaphragm valves are: resisting to corrosion and abrasion, absoluta watertigh and litle cost for maintenance. Seal is done by a membrane that´s pressed by a special pattern embólus against a curve surface seat. Althoug it´s a vertical seat valves, the lost of pressure is minimum in due to the pattern of body and the membrane´s bend. A lot of kinds of materials for the body covered or not, and the differents qualitys of membranes are the reason for these valves can work even in the most difficults conditions. MATERIALS: BODY: Cast Iron, cast iron covered with ebonite; rubber, Neopreno, halar stainless steel. MEMBRANES: Natural rubber, Neopreno, EPDM, Butilo, Perbuna, Hypalon, Viton and Teflon.
